TACKING MECHANISM FOR PULLING-OVER MACHINES.

Application filed July 16, 1912.

To all whom it may concern:

Be it known that ll, RONALD F. MoFnELY, a citizen of theUnited States,residing at Beverly, in the county of Essex and State of Massachusetts,have invented certain Tmprovements in Tacking Mechanisms forPulling-Over Machines, of which the following description, in connectionwith the accompanying drawings, is a specification, like referencecharacters on the drawings indicating like parts in the several figures.

This invention relates to machinery for inserting fastenings andparticularly to tack supplying and distributing mechanism for gangtacking machines and is embodied in an improved construction of thesimilar mechanism of my prior application, Ser. No. 585,069, filed Oct.3,1910.

The objects of the invention are to pro vide greater range in the use ofthe tacking mechanism and perfection of construction.

Tn the earlier machine symmetrical tacking only was provided for but Ihave found that with the development of markedly right and left lastsconditions arise requiring more tacks on one side of the shoe than onthe other or, sometimes, a different arrangement of the tacks on theouter side from that which is best adapted for holding the upper inpulled over condition on the inner side of the shoe. In addition tomaking provision for these requirements the invention includes noveldetails of construction and combinations of parts which will appear inconnection with the following description of the illustratedconstruction and will then be pointed out in the claims.

Figure 1 is a perspective view of the tack supplying and distributingmechanism of a pulling-over machine embodying this invention. Fig. 2 isan enlarged detail partly broken away to, show features of the tackseparator construction. Fig. 3 is a detail of one of the adjusters.Figs. 4: to 12 show different arrangements of tacking made pos sible bythis invention. Fig. 13 is a perspec tive view showing the connectionbetween the removable end block and the raceway structure which preventsthe removal of the end block when the separator is in a position whichwould permit separated tacks to drop out.

The framework 2 forms bearings for the axle of a hopper 4 which isoscillated by mechanism which may be like that described Specificationof Letters Eatent.

Patented Apr. 13, 1915.

Serial no. 709,704.

in United States Letters Patent No. 1,107,337, granted August 18, 191 1on an application filed by me, and serves to actuate the multipleclearers in the casing 3 and to reciprocate the tack separator slide 5across the end of the raceway structure 6 which has grooves for carryingseven lines of tacks. Wlth normal adjustment the separator slide, by itsfingers, picks seven tacksfrom the raceway and delivers them to theseven tack conductors which are numbered in Fig. 1 for insertion in theshoe as indicated in Fig. 4.

Associated with the 1st and 2d raceway groove is a tack controller and aduplicate controller is associated with the 6th and 7th groove. Thecontroller is shown enlarged in Fig. 2 and again in Fig. 3 and comprisesan endwise movable block guided in the raceway structure and arranged tobe projected through into the raceway at either end alternatively butshort enough so that 1n its central position it allows uninterruptedmovement of tacks down both grooves. The upper edge of the controllerblock 10 is toothed and is engaged by a lever 12 capable of turning onscrew 14 and having its tail formed on the under side as shown in Fig. 3with a central groove and beveled lateral edges. A spring pressed pin 15will engage the groove to hold the lever central for the tacking shownin Fig. 1 or will retain the lever shifted toward the right or the leftfor the tacking shown in Figs. 5, 6, 7, 8, 10 or 1.1. The lever can beshifted by an operators fi icilger but is normally covered by a swingingThe controller and adjusting means associated with the 1st and 2draceways can be adjusted centrally for both the 1st and 2d tacks to besupplied and thereafter driven as in Figs. 1, 10 and 11 or for one orthe other to be withheld as in Figs. 5, 6, 7, 8, 9 and 12. The twocontrollers provide independent adjustment for the tacks at the rightand left sides of the machine and therefore for right and left shoes.

Referring to Fig. 13, the end block 20, which is removable from theraceway block by manipulation of the locking devices 22 as described inmy earlier United States Letters Patent, 1,002,422, granted Sept. 5,1911, to afford access to the slide 5 and the tack separating plate 26and other devices associated therewith, is formed with a longitudinalgroove 24 from which lead transverse ways 25. The reciprocatingseparator plate 26 has on its lower face lugs 28 which can move in thegroove 24 and permit the end block 20 to be removed only at such time inthe cycle of the separating devices as the lugs are in alinement withthe ways 25. These lugsare so located that they prevent the removal ofthe end block while the mouths of the slots 30 in the separator plateare opposite the raceway grooves, in which position, in the earlierconstruction, excess tacks would slide into the slots 30 and require tobe removed. The present improvement obviates this difliculty.

In the use of the machine it is customary for the operator to pull overthe right shoes of the case or lot and then the left shoes. He thereforeexamines his style and his instruction card and makes his adjustment ofone or the other or both of the controllers 10 according to therequirements of his work which he is then able to fasten by tackslocated at the particular points where they are needed to hold the upperin pulled over position and to leave it free where it does not requireto be fastened or when it is advantageous that it be allowed to settleback, after being pulled, to obtain the proper drafting of the uppermaterials before lasting. This invention also effects an economy in shoemanufacturing because the driving of unnecessary tacks, heretoforesometimes unavoidable in order to get the necessary ones, is obviated.

Having fully described my invention, I claim as new and desire to secureby Letters Patent of the United States:

1. A machine of the class described having, in combination, gangmechanism for supplying and distributing tacks including a racewaystructure having a plurality of tack grooves the walls of which supportthe heads of the tacks and are spaced apart to receive the stems of thetacks, a multiple tack separator, independently adjustable devicesarranged to extend transversely across the tack grooves below the tackhead supporting surfaces thereof for withholding the supply of tacksdown a plurality of the grooves to the separator slide and means forsliding said devices across said grooves.

2-. A machine of the class described having, in combination, means forsupplying tacks for driving at the opposite sides and at the toe end ofa shoe, and a tack controller associated with the supplying means foreach side of the shoe and each adapted by independent adjustingmovements to suspend the insertion of tacks from one or another of aplurality of tack raceways for the same side of the machine.

3. A machine of the class described having, in combination, gangmechanism for supplying and distributing tacks including a racewaystructure having a plurality of tack grooves and a tack controller 10located with clearance between two grooves and movable to stop progressof tacks down either groove.
